Batman: Arkham City is loosely based on Unreal Engine 3, while the DirectX 11 functionality was apparently developed in-house. With the addition of these features Batman is far more a GPU demanding game than its predecessor was, particularly with tessellation cranked up to high.

Once again the GTX 680 takes a respectable lead over the 7970, this time beating AMD’s top card by 13% at 2560, and coming very close to cracking 60fps here. The performance gains over the GTX 580 are also solid, with the GTX 680 leading by 34% or better.

Hi, liked the review but are missing a few things, though I expect them to be reviewed at a later time in a new article. Like the improved multi-screen support, SLI, overclocking and things like that.

But I would like to know more about this turbo as well. What I am courious about is if it will boost minimum framerate as well as average framerate, or if the GPU is so taxed when it hits minimum framerate that it won't have anything extra to offer up to its turbo.Reply

Just a comment on the power draw - I wonder if you could test the 680 and 7970 in a different game, say for example Batman of BF3. The reason for this is due to the 7970 winning in Metro, while losing in most of the others and I wonder if there is something going on regarding power draw.Reply

What's different is AAA is used, as well as the Sandy E runs stock at 3,300 and is not overclocked. What appears to be a big problem for AMD cards is they have been offloading work to the cpu much more than the Nvidia cards, and even more so in CF v SLI, so when you don't have a monster CPU with a monster overclock to boot the AMD cards lose even worse.Reply
